I can't either. However, I think they are quite common in America. Also in some countries where baking isn't common, it's not easy to get the ingredients. I've lived in China and Japan and it was normal to buy Betty Crocker cake mix because butter and sugar weren't so common (and expensive).

Seems odd to me as well, some mums on my fb put proud pictures of 'baking with the kids' and it is always a packet mix. I mean fine on occasion and it is an easier way of getting to the decorating stage but it's not really teaching your child to bake is it?

The exception being Betty Crocker cookie mix, I've tried countless cookie recipes. None of them have ever matched up to the amazingness of Betty Crocker cookies!

We went to stay with some American friends years ago and the dd had made the pudding. They kept bigging it up and we were expecting something incredible. When it was placed on the table it was the equivalent of Angel Delight with whipped cream on top

Another conversation with an American friend about muffins she'd said were homemade were actually mix in a carton then you add milk and shake !

I wasn't being sniffy as cake is cake I don't mind how it arrives on the table but it did make me chuckle

My new next door but 2 neighbour is American and she begs for invitations if I am baking. She had never seen crumble topping being made, didn't know you could make it. It comes in packets and is inscrutable, apparently.

She has brought US products to me and we have had US : UK Bake Offs, force other neighbours to taste test. Sadly I am not winning by as large a margin as I expected - some of those packet mixes are good

I am about to show her how to make suet pastry... the local butcher is going to show here where the suet comes from - and the kidneys

I used to get a gluten free chocolate muffin mix which was really lovely, but I've since found a recipe which is just as good, so now I use that.

In America, aren't most of the measurements by volume, which is less accurate than by weight (i.e. It varies depending on how tightly packed the ingredient is) so recipes are, in the main, less reliable than in the UK, where measurements are by weight.
